l ELECTRICAL WATER-HEATER.

To all whom it may concern:

Be it known that I, HARRY Him, a citi- -zen of the United States, residing at St.

. clear, and exact (lescripltion, such as will enand through the same.

able others skilled in t e art to which it appertains to make and use the same, reference eing had to the ac'corn anying drawings, forming part of this spec' cation, in which- Figure 1 is a vertical sectional view thrbu himy improved electrical water heater; I ig. 2 is a horizontal sectional view This invention relates to a new and useful im roveinent in electrical water heaters, the ob ect being to construct a device of the character described which is capable of being adjusted from the exterior, whereby the contiguous faces of the electrodes may be moved toward or from each other for the purpose-of regulating the available space throu h which the water to be heated passes. It has been determined that waters rom difler'ent localities possess difierent resisting properties so far as currents of electricity are con cerned, and consequently difi'erent waters which are to be heated to the same or approximately the same degree of heat require different adjustments of the electrodes.

In the drawings, 1 indicates the casing or shell provided with a water inletopening or tap 2 and awater exit opening or tap 3. One end vof this casing is open so that the electrodes may be bodily removed from or in- I sorted into the shell.

4 is a capplate covering the open end of the casing, said cap plate being secured in position by suitable fastening devices and insulated from the shell 1.

5 is the outer electrode, preferably in the form of a'cylinder having a tapered opening throughout its length, said electrode being supported from the cap 4 by suitable shouldered insulating posts 6. Through these posts 6 passelectrical conductors 7 having appropriate shoulders to prevent cndwise movement in the posts, the outer ends of these conductors being provided with suitable threads to receive nuts 8 which form binding posts for the connection of the wire.

These conductors 7 are preferably insulated from the cap piece 4.

9 is a ring of insulating material supported in a groove in the upper end of the outer elecpecif cation of Letters Patent. Application filed July 29, 1907. Serial No. 386,163. 4

I am aware that minor changes in the con struction, arrangement and combination of I the several parts of my device can be made and substituted for those herein shown and described without departing from" the nature and principle of my invention.

. Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent 13:

' 1. In an electrical water better, the combination with a shell or casing, of a cylindrical outer electrode arranged therein, a

solid inner electrode arranged within the cylindrical electrode and providing a space for the passage of water therebetween and said outer electrode, said shell or casin being provided at its upper end with a disc arge opening for the heated water in axial ahnement with the inner electrode, and an insulation an the upper wall of the shell or casing to ring interposed between the'outerelectrode 110 I prevent the water from flowing over the upper edge of the outer electrode and thus said electrode in position in BEST AVAILABLE cos;

secured tQrSfild. cap piece for supporting said electrode in position; scribed. v

3. Inan electrical water heater, the combination'with a shell or housing, of an electrode arranged therein, a post for sup orting said s ell or substantially as dehousin and means on said ing sai electrode; substantia ly as described.

. outer cy 4. In an electrical water heater, the combination with a shell or housing open at one end, a ca piece for closing said open end, an drical electrode, insulation posts for supporting said cylindrical electrode 1n position, electrical conductors passing through said post and said electrode, an inner electrode, a post for sup orting said inner electrode in position, an means on said post for adjustin said inner electrode; substantially as deseri ed.

5. In an electrical water heater, the combination with an o e'n-ended shell or casing, of a cap piece for e osing the open end of said shell or casing, two electrodes supported from said cap piece, one of said electrodes, the

outer, being in the form of a cylinder and be 'ing spaced from the ene wall of the shell or lHHlSlllg by an insulat on ring, and the other 0st for adjust- Y of said electrodes being supported by a post from the cap piece, and means cooperating with said 0st for ad usting the cap piece; substantia. y asdescribed.

6. In an electrical water heater adapted royided with e flow of wa- 1 for heating flowing water and inlet and outlet'passages for t I ter therethrough, the combination with ,two electrodes so located as to leave a liquid channel therebetween, one of said' electrodes being adjustable fromthe exterior, with its face at an angle to its line of adjustment, and exteriorly arranged means for adjusting said electrode; substantially as described.

7. In an electrical water heater adapted for heating flowing water and provided with inlet and outlet passages for the flow of water therethrough, the combination with an electrode havin an inclined face, of an adjustable electrode having an inclined face at an angle to its line of adjustment and so disposed as to leave a passage between said electrodes, and exteriorly arranged means for adjusting the last-mentionedelectrode so as to regulate the area of said assage, thereby regulatin the quantity 0 water passin through t e same; substantially as describe In testimon whereof Ihereunto aflix my signature in t e presence of two witnesses, this sixteenth day of July 1907.
